A ''' code name''' or '''cryptonym''' is a word or name used, sometimes clandestinely, to refer to another name, word, project or person. Names are often used for military
purposes, or in espionage
. They may also be used in industrial counter-industrial espionage
to protect secret projects and the like from business rivals, or to give names to projects whose marketing name has not yet been determined. Another reason for the use of names and phrases in the military is that they transmit with a lower level of Chinese whispers|cumulative errors
over a walkie-talkie
or radio link than actual names.
